Check out Network Probe.  That is what I use.  Simple, inexpensive
(there is
a free version) and helped me track down several users who were
streaming
audio and using AOL instant messenger.

Not for free, but Sniffer Pro can tell you a lot of things that are 
happening and it has also "layered". So one can look at the Data Link, 
Network, Transport or other layers and see what protocols are being 
used, see top-talkers in each protocol, bandwidth used, different 
percentages and so on... It has a lot of info.
  At first I thought that it is not very good tool, but over time I have

changed my opinion. It has lot of good info, through which is easy to 
navigate and see what could be happening.

  Just a thought -- Tomas
